Reaction Steps

To a solution of 8-methyl-6-(3-nitrophenyl)-8H-pyrido[2,3-d]pyrimidin-7-one (0.35 g, 1.2 mmol) in EtOH (10 mL) was added Pd (0.2 g). The mixture was stirred under an atmosphere of H2 (30 psi) for 1.5 h. After removal of the catalyst by filtration, the solvent was evaporated under vacuum to give 6-(3-aminophenyl)-8-methyl-8H-pyrido[2,3-d]pyrimidin-7-one (150 mg, 50% yield) as a white solid. 1H NMR (300 MHz, DMSO-d6): δ 9.08 (d, J=4.2 Hz, 1H), 8.18 (s, 1H), 7.85 (m, 1H), 7.80 (d, J=5.4 Hz, 1H), 7.64 (t, J=7.8 Hz, 1H), 7.43 (d, J=5.4 Hz, 1H), 3.85 (s, 3H).
